Absolutely a necessity,A high quality well made tool set, essential when working with JIS screws

These are JIS drivers folks (well two of them anyway.) They were new to me not long ago, but there is a difference in how they grab the screws... JIS screws are a Japanese standard and are found on many electronics items. I tried these on the back of my Notebook along side a brand new made Phillips of the appropriate size, and the JIS works better (it stays more firmly planted in the screw instead of trying to "cam" out.) This is the best set of screwdrivers I've ever purchased and blows the cheap Chinese garbage out of the water with brilliant Japanese quality. This is a great screwdriver set.Recommended.Fast shipping, and at a great price. View detail
